## Executive Summary

Edulas (`https://edulas.xyz`) is an operating system and automated proctoring platform designed specifically for university computer science and engineering departments. It unifies multi-language WebAssembly IDEs, 40-desk real-time grid proctoring, AST plagiarism analysis, and automated test-suite grading into a single browser-native application.

## Detailed Component Specifications

### 1. Zero-Login Room PIN Entry (`/student/join`)
- **Problem Solved**: On shared campus lab PCs, student account logins cause session-stealing risks and login delays.
- **Protocol**: Professors generate a 6-digit session PIN. Students input the PIN alongside their name/student ID. The system issues a 5-minute encrypted session cookie scoped strictly to the active lab room.

### 2. Professor Command Studio (`/prof`)
- **Proctoring Grid**: Displays a 40-desk matrix showing live status indicators:
  - 🟢 **Coding**: Active keystrokes within workspace.
  - 🟡 **Idle**: Inactive for > 60 seconds.
  - 🔴 **Focus Loss**: Tab switch, window defocus, or copy-paste detected.
  - 🟣 **AST Flagged**: Structural code similarity > 85%.
  - 🔵 **Help Requested**: Student raised virtual hand.
- **Broadcast System**: 1-click modal overlay dispatched to all student monitors in the room.

### 3. AST Plagiarism Analysis Engine
- **Parser**: Translates student source code into Abstract Syntax Trees (AST).
- **Comparison Algorithm**: Normalizes node types (variable definitions, loops, conditional branches) and computes tree edit distances.
- **Resilience**: Identifies plagiarized code even when students rename variables, reorder independent statements, or change comments.

### 4. Cortex Socratic AI Engine
- **Behavior**: Acts as a virtual teaching assistant. Guided by Socratic principles, it highlights compiler syntax errors and logic bugs without revealing solution code.

## Security & Compliance Architecture

- **FERPA Compliance**: Private app routes (`/prof/*`, `/student/*`, `/sessions/*`, `/drop/*`) inject `X-Robots-Tag: noindex, nofollow, noarchive` headers. Student grades and names are strictly hidden from search engine indexing.
- **Crawl Budget Protection**: Ephemeral query paths (`/*?pin=*`, `/*?code=*`) are disallowed in `robots.txt`.
- **Canonical Routing**: All legacy host requests (`campus.aimd.app`, `campus.aimd.site`) return HTTP 301 redirects to `https://edulas.xyz`.
